Our approach is the so-called reducibility method, which was initially developed by Dinaburg-Sinai [1]}, Eliasson [2]}, further developed by Hou-You [3]}, Avila-Jitomirskaya [4]} and Avila [5]}, [6]}. Our result is based on the reducibility results in [7]}, [8]}, [9]}, [10]} for higher dimensional quasi-periodic cocycles.
